The

s Figure '5 is a section ontheflline 5-5 of Figure air is also forced through troughs ll in the filler sole 8 and emerges into the shoe through suitable openings in said troughs beneath the toe and forward portion of the foot.

In order that the air thus forced forwardly by each walking step can be medicated for treatmentof the foot for comfort, use is made of a noncompressible auxiliary member or medicament container 2| which is made of metal or hard rubber or any suitable material and is provided with a plurality of pockets or chambers 25, perforated at .their sides and ends as at 26 and arranged to be filled with a suitable plastic medicament or deodorant, the fumes of which can escape through the openings 26 to condition the air as it bathes the chambers in its passage thereby. The chambers can be filled through the innersole of the footwear through openings 21, one of which is shown in Figure 1 The openings 21 may be dispensed with in the event that a medicament of long life is employed which does not need replenishing within the ordinary life of a shoe. The

medicament container 24 comprises a flat plate portion 28 which rests on the outsole 6 and holds the chambers in position in the space H in the shank and heel filler II so that said chambers are directly in the path of the air being forced forwardly. A turned over edge 29 on the plate 2B abuts one side of the shank and heel filler space and helpsmaintain the device in position.

The forward end of the plate 28 is provided with open-ended parallel channels 30 which seat in the ends of the passages 20 and maintain the same open so that the air can pass freely.

The adjacent ends of the filler sole and the shank and heel filler are tapered, the latter so that compression of the end thereof will not fill the space in front of the channels 30 and the former 'so that air. in passing out of the shank and heel filler will pass through the holes 22 in the filler sole and along the slots thereof to be forced beneath the toes of the wearer of the shoe or article of footwear, it being understood that my invention applies as well to any type of footwear, the word shoes being used to indicate footwear in all classes.

' It is understood that the shank and heel filler may be sold for use in the shoe without building it into the shoe as illustrated and also the medicament container may bedispensed with or may be used with the shank and heel filler in the bottom-of the shoe as desired. It isevident also that the chemical element container can be made r of the same material as thefiller sole in varying degrees of hardness.

It is evident therefore that I have provided a medicated filler sole which lends itself readily to constant treatment of the feet during walking, is beneficial to the wearer and is not cumbersome, can be readily incorporated in the shoe construction without detracting from its appearance or in any way changing its shape. To the wearer of the shoe the only evidence of its presence is its comforting effect and medicating influence.

My invention is not-to be restricted to the precise details of construction shown since various changes and modifications may be made therein without departing fromthe scope of the invention or sacrificing the advantages derived from its use.

10 What I claim is:

catingthe air comprising a medicament, a medicament container including a plate adjacent one face of said filler and a perforated medicament housing on the plate extending into said filler and disposed in the path of air being forced through said passages, and said inner sole having openings through which the medicated air can reach the foot.

2. In footwear, in combination, inner and outer soles, a filler sole, a compressible'shank and heel filler, said fillers beingpositioned between said inner and outer soles, the shank and heel filler being shaped to provide a plurality of longitudinal air passage defining walls, air being forced through the passages forwardly by the diminishing size of said passages as the shankand: heel filler is compressed from back to front by walkthrough said passages and said inner sole adjacent the forward end of said shank and heel flller having openings through which the medicated air can reach the foot.

3. In footwear, in combination, inner and outer soles, a compressible shank and heel filler between the soles shaped to provide a plurality of air passage defining walls, air being forced forwardly through the passages by the diminishing size of the latter as the filler is compressed from back to front by walking action, a medicament -container disposed in the path of the forwardly moving air comprising a perforated housing in which a medicament agent is held and said inner sole having openings for leading medicated air to the foot.

4. In footwear, in combination, inner and outer soles, a compressible shank and heel filler between the soles shaped to provide a plurality of air passage defining walls, air being forced forwardly through the passages by the diminishing size of the latter as the filler is compressed from back to front by walking action, one of said walls extending around the sides and back of said shank and heel filler, and some of said walls being cut-away to provide a space in said shank and heel filler, a medicament container in said space and in the path of forwardly moving air and said inner sole having openings for leading the medicated air to the foot.

5. In footwear, in combination, as set forth in claim 1, wherein said walls are slotted to provide air grooves connecting said air passages and said grooves extending at rearwardly converging angles relatively to said passages.

6. In footwear, in combination, as set forth in claim 2, wherein said plate presents channels extending therefrom and into some of said air passages for preventing closure thereof when said shank and heel filler is compressed.
